Dennis advanced to the next round of competition following a thorough four-round thrashing of unbeaten Steve Vukosa. The final fight of the night was perhaps the most anti-climactic as well. Dennis came in with a vengeance, determined to prove he's better than the raw version that suffered a stunning knockout loss to Nat Heaven (who was stopped by Fedosov on this show) in this very venue last April.

Vukosa was dropped in round three and ultimately knocked loopy. The 38-year old - who was out of the ring for 12 years before returning last year - could never fully recover, to the point of thanking referee Charlie Fitch for stopping the fight when he did.

The official time was 2:52 of round four.

Dennis has now won two straight, improving to 10-1 (8KOs). Vukosa - who owns a win over late tourney entrant Jason Estrada - falls to 10-1 (4KOs).

An early end was badly in need following two straight fights going into an extra round, on a telecast delayed by the lead-in college basketball game going into overtime. Andrey Fedosov delivered big time, scoring a 1st round knockout over Nat Heaven.

Fedosov has been tabbed by many as the odds-on favorite to take the heavyweight bracket. The 28-year old Russian boxer certainly looked the part, flooring Heaven midway through the round with a left hook then again just before the 10-second warning bell.

Heaven (9-2, 7KOs) was in the process of rising from the canvas when referee Benji Esteves decided his night was done. The call didn't sit well with the boxer, who literally rolled out of the ring in disgust, though eventually returning if only to voice his disgust.

With the win, Fedosov (25-4, 20KOs) will face Lenroy Thomas in the semifinals on April 3.

Thomas
overcame strange scoring to claim a decision win over Jason Estrada, although it required the fight going into overtime. Action was declared even through six rounds, forcing the heavyweights to fight in a "drawbreaker" 7th round to determine a winner.

The extra three minutes showcased what Thomas (19-3, 9KOs) had done since round two - tattoo the out-of-shape Estrada, who accepted the fight on late notice, coming in at a career heaviest 261 lb. T
he bonus round spared the judges of total embarrassment, Thomas (19-3, 9KOs) picks up the most notable win of his career to date.

Razvan Cojanu overcame a strong finish from Ed Fountain, edging the unbeaten heavyweight in yet another bout that went to overtime.

Cojanu managed to win 58-56 on one card, but was overruled by matching scores of 57-57 to force the bout to a 7th round "drawbreaker" session to determine the winner. Fountain (10-1, 4KOs) enjoyed a nice late round surge, but it was only enough to extend the fight three more minutes but not enough to retain his "0" or survive the opening round of the tournament.

The win is the 13th straight for Cojanu since losing his pro debut four years ago.
